How two different blocks can be made from the same pieces.
The multitude of setting options.
A third block.
Actually, youall came up with a lot more!
I hope those who played along have enjoyed the exercise. It was fun to see your guesses along the way. A couple of you were close in expecting there to be positive and negative results. So without further ado ... ta-dah:
THE FINAL SOLUTION
Each block is constructed from four units: Two rail units, one large triangle square, and one 4-patch unit. Pay close attention to the orientation of the triangle squares. Assemble like a 4-patch, sewing a rail unit to the 4-patch unit and the large triangle square to a rail unit. Press toward the rail units. Spin the final seam (or press open).
Why spin the seams? When you spin the seams of a 4-patch construction, you can orient your block in any direction and it will automatically nest with the next block. You're skeptical, I know. But try it, it works! I will say that, depending on how you assemble the blocks into a quilt, the seams where rail units meet end-to-end may not nest. In that case I flip the seam at the intersection and press the seam into submission.
As I said before, you could make a quilt from all A blocks or all B blocks, but the more interesting construction comes from alternating A and B. Because of the strong diagonal of the blocks, you can do just about anything you could do with a plain HST or a light/dark log cabin block.
For example, Furrows (or is this Sunshine and Shadows?):
Or how about Barn Raising:
Shift and twist a few blocks and you get this:
Or the reverse:
Check back tomorrow to see a finished quilt (not this one, though) and learn about the bonus block.
To give credit where credit is due, this mystery was inspired by a block called Hopkins Square in Judy Hopkins' book 501 Rotary-Cut Quilt Blocks (Martingale & Company, Woodinville, WA, 2008).
And if you want more setting inspiration, check out Judy Martin’s Log Cabin Quilt Book (Crosley-Griffith Pub. Co., Inc., Grinnell, IA, 2007).
I hope you had fun and I would love, Love, LOVE to see pictures of any finished quilts.
